Optical Haar wavelets are generated by zone plates that are designed to realize the bipolar nature of Haar wavelets. We present a circular Haar wavelet in two-dimensional space, which can extract the edge and corner features simultaneously, and characterize its properties with computer simulations. A comparison with rectangular Haar wavelets is also given.
